Storyline: Mar Vista coach Tyler Arciaga doesn’t know what got into Hill last week when he pounded Valley Center for 244 yards and three touchdowns on 18 carries in a close defeat. But Arciaga wants Hill to channel whatever it was again this week. He’ll need to against a good Serra team that proved it can light up the scoreboard, producing 42 points in a win over Monte Vista. The Mariners are a bit bigger up front on the offensive line, so Hill should have decent holes to run through and opportunities to create magic.

Key stat: To put his performance in perspective, Hill has already eclipsed one-fourth of his season total from last year — 847 yards on the ground — in just the first week. That’s a 13.6-yard average per attempt and a touchdown every six carries.

Quotable: “Upstairs, he’s really bright, in the classroom and on the football field,” said Arciaga, who’s in his first year at Mar Vista. “He’s a downhill type of back that has a blend of speed and power. Jimmie is quick but is capable of breaking arm tackles and getting those tough yards for us. Being a one-back offense, instead of using the double wing like last season, we’re more traditional and he’s the focus back.”

RAY LYONS

Crawford

Sr. | RB | 5-10, 180

Lyons had touchdown runs of 81, 28, 26 and 18 yards last week. A second consecutive win by the Colts is contingent on a similar performance.

MARC GALLANT

Del Norte

Sr. | RB | 5-9, 175

The all-leaguer eats up real estate for Del Norte, bursting on the varsity scene last season with 1,192 yards rushing and 10 touchdowns.

REY OSUNA

Olympian

Sr. | LB | 5-8, 170

Anchoring an inexperienced defense, Osuna must be disruptive and active against Francis Parker and its spread, read-option offense.

JALEN DAVIS

Helix

Sr. | WR-DB | 5-11, 170

The Highlanders were unable to sustain any drives against Punahou, but Davis has Velcro hands and can be a nightmare to slow down in open space.
